build in dev profile by default, release if requested

[nschloe]

I'd like my project to build in the dev profile by default. To this end, I added

[tool.maturin]
profile = "dev"

to my pyproject.toml. However, I can't seem to override this. maturin build --release still builds in dev mode.

Any hints?

Using --profile release appears to work.

I tried to fix this in #2568 but it's breaking change so it won't be merged until maturin 2.0.

So please use the workaround for now.
